I put the 3 new roms in and some coils, lights and display activated on and off at random. the 4 leds did flash at different intervals as well. However after about 15 seconds, it went back to its normal 4 leds flashing, no coil movement and no display. The only difference is that the playboard lights stay on.
I checked that it was only 5 volts to the rom chips
Another stange thing is that the test switch has being bypassed with the 2 wires soldered together, any ideas? I bought this as is and therefore have never seen it going
